Remember the major security hole found in iOS 4.1 from a few years back that would allow someone to access your contacts even though the phone was locked with a passcode? Well it appears someone has figured out another way to exploit a serious flaw in iOS 6.1 that would enable them to have access to your phone module – where they can then view/edit contacts and make calls. As per Gizmodo:

First you have to pretend to turn the phone off, then make an aborted emergency call, then a quick bit of off button and cancel pressing. That boots you into the full phone app where you can pretty much call or message anyone you like.

Until Apple patches this in a future update, your safest best is to keep your iPhone close by 24/7. Check out the video on how the hack is done after the break.
